Description

  The present invention relates to allocation evaluation for determining which type of articles among a plurality of types of articles is allocated to each automatic warehouse facility when storing a plurality of types of articles in a plurality of automatic warehouse facilities. Relates to the device.

  The automatic warehouse facility sequentially stores a plurality of types of articles that are carried in the article storage shelf, and stores any type of articles among the plurality of types of articles in the article storage shelf. When goods are delivered, only the type of goods requested to be delivered out of a plurality of kinds of goods is delivered, and the kind of goods requested to be delivered is delivered from the goods storage shelf to the goods delivery location. ing. The article is, for example, a pallet on which a plurality of articles are placed with the same kind of articles stacked. At the article unloading location, a picking operation for taking out a required number of articles from the delivered pallet and storing them in a shipping case or the like is performed, and a plurality of articles are shipped together in a shipping case.

The automatic warehouse facility is provided with an article carry-in place for carrying in articles, an article carry-out place for carrying out articles, and a plurality of article storage shelves. As the article storage shelves, for example, a plurality of sets of a pair of article storage shelves are provided. For each set of article storage shelves, a storage part for placing articles stored in the article storage shelf and a delivery part for placing articles delivered from the article storage shelf are provided. For each set of article storage shelves, a first article transport device (for example, a stacker crane) that transports articles between the storage unit and the plurality of storage units and between the plurality of storage units and the output unit is provided. ing. A plurality of second article conveyance devices (for example, tracked article conveyance vehicles) that convey articles between the article carry-in location and each entry unit and between each delivery unit and the article carry-out location are provided. Then, when storing the article carried into the article carry-in location in the article storage shelf, the second article transport device conveys the article from the article carry-in location to any of the plurality of warehousing units, and the first article transport device is the warehousing unit. The article is conveyed from one to a plurality of storage units in the article storage shelf. When unloading an article from an automatic warehouse facility, first, an article of the type requested to be unloaded is selected from the stored articles, and the first article transporting apparatus transports the selected article from the storage unit to the unloading unit. 2 The article conveying device is configured to convey the article from the unloading unit to the article unloading location (see, for example, Patent Document 1).
In such automatic warehouse equipment, as the number of articles handled and the number of types of articles are increasing, the amount of stored articles is required, so in addition to the existing automatic warehouse equipment, an automatic warehouse equipment is newly installed. Some are equipped with a plurality of automatic warehouse facilities by expanding.

In the case where a plurality of automatic warehouse facilities are provided, there are cases in which the automatic warehouse equipment has different delivery capabilities indicating how many articles can be delivered in a unit period. For example, when an automatic warehouse facility is newly added, the transfer capability of the first article transfer device or the second article transfer device is higher than that of the existing automatic warehouse facility, and is newly added to the existing automatic warehouse facility. The automatic warehouse equipment has a higher delivery capacity.
When the warehouse capacity per unit period is different between automatic warehouse facilities, if any kind of goods among a plurality of kinds of goods is stored for each of a plurality of automatic warehouse equipment, Cause problems.

For example, when issuing the same number of articles, the automatic warehouse equipment with a low output capacity per unit period takes longer time for the output work, whereas the automatic warehouse equipment with a high output capacity per unit period The time required for the delivery work can be shortened. Thus, for example, when the same number of articles are delivered from each of a plurality of automatic warehouse facilities as a one-day warehouse operation, the automatic warehouse equipment having a lower output capacity per unit period has a higher output capacity per unit period. Outgoing work end time is later than that of high automatic warehouse equipment. In this way, for example, the one-day warehouse work end time may vary depending on the automatic warehouse equipment.
In addition, an automatic warehouse facility with a high delivery capacity per unit period can be delivered efficiently even if the number of storable items is increased. However, when an article is delivered from a plurality of automatic warehouse facilities, the probability that the article is delivered from an automatic warehouse facility having a large number of articles that can be stored increases. Therefore, if the number of items that can be stored in the automatic warehouse equipment with a high output capacity per unit period is larger than the automatic warehouse equipment with a low output capacity per unit period, the automatic warehouse equipment with a high output capacity per unit period There is a risk that the number of issues will increase and the issue capacity will not be able to keep up. As a result, the automatic warehouse equipment with a high output capacity per unit period has a slower output work end time than the automatic warehouse equipment with a low output capacity per unit period, and the one-day storage operation end time varies depending on the automatic warehouse equipment. Sometimes.
As described above, when the time of completion of warehouse work for one day differs depending on the automatic warehouse equipment, even if the work of delivery at a certain automatic warehouse equipment is completed, the goods to be delivered until all the warehouse work at the automatic warehouse equipment is completed. The situation is not complete and the goods cannot be shipped. Therefore, there is a possibility that the problem that the goods cannot be shipped efficiently occurs.

Therefore, in storing a plurality of types of articles in a plurality of automatic warehouse facilities, each type of the plurality of automatic warehouse facilities is not stored in any type of the plurality of types of articles. It is required to determine which kind of goods among a plurality of kinds of goods can be assigned to the automatic warehouse equipment, so that the exit time can be set to the same time in the plurality of automatic warehouse equipment. ing.
The present invention has been made paying attention to such a point, and the purpose thereof is to make the exit operation end time the same for a plurality of automatic warehouse facilities, so that a plurality of types are provided for each automatic warehouse facility. An object of the present invention is to provide an allocation evaluation apparatus that can determine which type of articles to be allocated.

In order to achieve this object, the first characteristic configuration of the allocation evaluation apparatus according to the present invention is to store a plurality of types of articles for a plurality of automatic warehouse facilities. An allocation evaluation device for determining which type of article to be allocated,
The plurality of automatic warehouse facilities are configured to have different delivery capabilities indicating how many articles can be delivered in a unit period, and the delivery information about the articles delivered in each of the plurality of automatic warehouse facilities Based on the delivery information input to the input means, a computing means for computing the number of times of delivery per unit period for each of the plurality of types of articles, and calculated by the computing means Storage means for storing the number of times of delivery, and storing a classification state when the plurality of types of articles are classified into a plurality of output frequency ranks in a form arranged in order from the type of articles with the highest number of issues per unit period. And an output means capable of outputting a calculation result calculated by the calculation means, and a division state change setting means capable of changing and setting the division state of the plurality of delivery frequency ranks. The storage means is configured to store a delivery number rank assignment pattern that determines which of the delivery number ranks among a plurality of delivery number ranks is assigned to each automatic warehouse facility, and the computing means is the storage unit. When the plurality of types of articles are classified into the plurality of delivery number ranks based on the classification state changed and set by the division state change setting means in the delivery number rank assignment pattern stored in the means, The automatic warehouse equipment is configured to calculate a delivery ratio between the automatic warehouse equipments from the total number of times of delivery of articles assigned per unit period of the automatic warehouse equipment, the output means to the computing means The output ratio is calculated so as to be output to the display means.

In other words, by classifying multiple types of goods in order from the type of goods with the highest number of issues per unit period into multiple issue frequency ranks, and by determining which issue frequency rank is assigned to each automatic warehouse facility It is possible to determine which kind of goods among a plurality of kinds of goods is assigned to each automatic warehouse facility. The delivery number rank assignment pattern defines which delivery number rank is assigned to each automatic warehouse facility, and this delivery number rank assignment pattern is stored in the storage means.
For example, when the worker changes and sets the classification status of a plurality of delivery frequency ranks by the classification status change setting means, the calculation means is in the classification status changed and set in the delivery frequency rank assignment pattern stored in the storage means. When a plurality of types of articles are classified into a plurality of delivery times ranks, the delivery ratio between automatic warehouse facilities is calculated. The shipping ratio calculated by the calculation means is output to the display means by the output means and displayed. Thereby, the worker can grasp what value the delivery ratio between the automatic warehouse facilities will be when the classification state of the plurality of delivery frequency ranks is set.

  When multiple warehouses have different delivery capacities per unit period, there is a difference in the time required for delivery between automated warehouses, and the time difference depends on the difference in delivery capacity between automated warehouses. Will occur. Therefore, if the ratio of delivery between automatic warehouse facilities is set so as to eliminate the difference in delivery capacity between automatic warehouse facilities, the delivery work end time can be set to the same time for multiple automatic warehouse facilities. . Therefore, the worker can understand the value of the delivery ratio between the automatic warehouse facilities when the classification status of the multiple delivery rank ranks is set to what sort status, The classification state can be changed and set repeatedly. As a result, if the delivery ratio for eliminating the delivery capacity difference between automatic warehouse equipment is the target delivery ratio, the delivery ratio between the automatic warehouse equipment displayed on the display means is the target delivery ratio. In addition, it is possible to determine what sort of state should be used for the sorting state of the plurality of delivery count ranks.

  Thereby, for example, in order to set the exit operation end time in a day to the same time in a plurality of automatic warehouse facilities, it is determined what sort state should be set for the plurality of exit rank ranks. be able to. As a result, it has been possible to determine which kind of article among the plurality of kinds of articles should be assigned to each automatic warehouse facility in order to match the delivery work end time with the plurality of automatic warehouse facilities.

  According to a second characteristic configuration of the allocation evaluation apparatus according to the present invention, the calculation means is based on the classification state changed and set by the classification state change setting means in the number-of-issues rank allocation pattern stored in the storage means. And calculating the filling rate in each automatic warehouse facility when the articles allocated to each of the plurality of automatic warehouse facilities are stored when the plurality of types of articles are classified into the plurality of delivery times ranks. The output means is configured to output the filling rate calculated by the calculation means to the display means.

  That is, when the worker changes and sets the classification state of a plurality of delivery frequency ranks using the classification status change setting means, the calculation means changes to the classification status changed and set in the delivery frequency rank assignment pattern stored in the storage means. Thus, when a plurality of types of articles are divided into a plurality of delivery times ranks, the filling rate in each automatic warehouse facility is calculated. The filling rate calculated by the calculation means is output to the display means by the output means and displayed. As a result, the worker can confirm that the filling rate in each automatic warehouse equipment does not exceed the appropriate value, and set the outgoing work end time to the same time in multiple automatic warehouse equipment. It is possible to determine what kind of classification state the classification state of the frequency rank should be.

In the third characteristic configuration of the allocation evaluation apparatus according to the present invention, in storing a plurality of types of articles in a plurality of automatic warehouse facilities, which type of articles among the plurality of types of articles is stored in each automatic warehouse facility. An allocation evaluation device for determining whether to allocate
The plurality of automatic warehouse facilities are configured to have different delivery capabilities indicating how many articles can be delivered in a unit period, and the delivery information about the articles delivered in each of the plurality of automatic warehouse facilities Based on the delivery information input to the input means, a computing means for computing the number of times of delivery per unit period for each of the plurality of types of articles, and calculated by the computing means Storage means for storing the number of times of delivery, and storing a classification state when the plurality of types of articles are classified into a plurality of output frequency ranks in a form arranged in order from the type of articles with the highest number of issues per unit period. Output means capable of outputting a calculation result calculated by the calculation means, and assigning to each automatic warehouse equipment when an article is assigned to each of the plurality of automatic warehouse equipment A target delivery ratio setting means capable of setting a target delivery ratio between automatic warehouse facilities for the total number of delivery times per unit period of the goods, and the storage means for each automatic warehouse equipment It is configured to store a shipping number rank allocation pattern that determines which shipping frequency rank among a plurality of shipping frequency ranks is allocated, and the calculation unit stores the shipping frequency rank allocation pattern stored in the storage unit. The number of goods delivered to each of the plurality of automatic warehouse facilities when the plurality of types of articles are classified into the plurality of goods delivery ranks based on the classification state stored in the storage means in FIG. The delivery ratio between the automatic warehouse facilities is calculated from the total number of delivery of the warehouse, and the requested delivery ratio is set by the target delivery ratio setting means. The storage unit is configured to change and set the division state of the plurality of delivery count ranks so as to be a rate, and the storage unit updates the stored division state to the division state changed and set by the calculation unit. It is in the point which is comprised so that it may memorize.

  That is, as described in the first feature configuration above, in order to set the delivery work end time to the same time in a plurality of automatic warehouse facilities, the delivery ratio between the automatic warehouse facilities is set to the delivery capability between the automatic warehouse facilities. The value is required to eliminate the difference. For example, the worker can set the target delivery ratio for canceling the delivery capacity difference between the automatic warehouse facilities by the target delivery ratio setting means for the delivery ratio between the automatic warehouse facilities. When the target delivery ratio is set in this way, the calculating means selects a plurality of types of articles as a plurality of delivery frequency ranks in the classification state stored in the storage means in the delivery frequency rank assignment pattern stored in the storage means. When the goods are classified into two, the delivery ratio between the automatic warehouse facilities is obtained, and the classification state of the plurality of delivery times ranks is changed and set so that the obtained delivery ratio becomes the target delivery ratio. The classification state of the plurality of delivery frequency ranks changed and set by the calculation means is updated and stored by the storage means. Thereby, the worker confirms the division state of the plurality of delivery frequency ranks updated and stored in the storage means, so that the delivery ratio between the automatic warehouse facilities becomes the target delivery ratio. It is possible to determine what sort state the sort state is.

  As a result, for example, it is possible to determine what sort state should be set for the division status of multiple delivery rank ranks in order to make the delivery operation end time in a day the same time in a plurality of automatic warehouse facilities. Therefore, it is possible to determine which type of goods among a plurality of types of articles should be assigned to each automatic warehouse equipment in order to set the exit work end time to the same time in a plurality of automatic warehouse equipments. It was.

  According to a fourth characteristic configuration of the allocation evaluation apparatus according to the present invention, each of the plurality of automatic warehouse facilities includes a first article transporting apparatus that transports an article stored in an article storage shelf to a shipping section, and the shipping section. A second article conveying device that selectively conveys the conveyed article to any one of a plurality of article unloading locations, and the computing means transfers the article to any of the plurality of article unloading locations by the second article conveying device. If the article is delivered once, the article is delivered once, and the number of times of delivery per unit period is calculated for each of the plurality of kinds of articles.

  That is, for example, in the case where the same type of articles are stacked and stored in the article storage shelf with a pallet on which a plurality of articles are placed, the pallet is transported to the article unloading location. In other words, one pallet may be transported to a plurality of article unloading locations. At this time, the pallet is transported to the unloading unit by the first article transport device, and is transported to a plurality of article unloading locations by the second article transport device. The computing means does not assume that the article is unloaded once when the article is conveyed to the unloading unit by the first article conveying device, but when the article is conveyed to any of a plurality of article unloading locations by the second article conveying device. Assume that an article has been issued once. Thereby, the number of times of delivery per unit period can be accurately calculated for each of a plurality of types of articles.

  A fifth characteristic configuration of the allocation evaluation apparatus according to the present invention includes, as the automatic warehouse equipment, a first automatic warehouse equipment and a second automatic warehouse equipment having a delivery capacity in a unit period higher than that of the first automatic warehouse equipment, The plurality of delivery frequency ranks are a higher rank with a higher number of issues per unit period, a lower rank with a lower number of issues per unit period, and a higher number of issues per unit period with the upper rank and the lower rank. The delivery number rank assignment pattern, which is comprised of three ranks, the middle rank being between, and stored in the storage means, assigns the middle rank to the first automatic warehouse facility and the second automatic This is the issue number rank allocation pattern determined so that the upper rank and the lower rank are allocated to the warehouse facility.

  That is, among a plurality of delivery frequency ranks, an article with a higher rank with a higher number of issues per unit period may be issued in large quantities, but the output capability in the unit period is higher than that of the first automatic warehouse facility. 2 By assigning to automatic warehouse equipment, it is possible to deal with a large amount of goods being shipped. If the middle rank is assigned to the second automatic warehouse equipment in addition to the upper rank, the rank with the highest number of issues per unit period will be assigned to the second automatic warehouse equipment in a state of being biased to the first automatic warehouse equipment. There is a possibility that the second automatic warehouse facility has a larger number of times of delivery than the warehouse facility. Therefore, the delivery number rank assignment pattern determined to assign the middle rank to the first automatic warehouse equipment and assign the upper rank and the lower rank to the second automatic warehouse equipment is a suitable delivery number rank assignment pattern, This suitable number-of-issues rank allocation pattern can be stored in the storage means. As a result, it is possible to accurately and suitably determine which kind of article among a plurality of kinds of articles should be assigned to each automatic warehouse facility in a suitable dispatch number rank assignment pattern.

An embodiment of an allocation evaluation apparatus according to the present invention will be described with reference to the drawings.

The input means 11 is configured to input delivery information about articles delivered at each of the first automatic warehouse facility 1a and the second automatic warehouse facility 1b. The delivery information at this time is information that can identify what kind of article is delivered and when the delivery time is. The calculation means 12 is configured to calculate the number of times of delivery per unit period (for example, one day) for each of a plurality of types of articles based on the delivery information input to the input means 11. Here, when the article is conveyed to any one of the plurality of article unloading locations 7 by the second article conveying device 9, the calculation means 12 assumes that the article has been delivered once, and for each of the plurality of types of articles per unit period. It is comprised so that the frequency | count of leaving may be calculated.
The output means 14 is configured to output the calculation result calculated by the calculation means 12. The display unit 15 is configured to display the output information output by the output unit 14.

  The storage means 13 stores the number of times of delivery per unit period for each of the plurality of types of articles calculated by the calculation means 12, and is arranged in order from the type of articles with the highest number of times of delivery per unit period. In this case, the classification state when the plurality of types of articles are classified into a plurality of delivery frequency ranks is stored. For example, as shown in FIG. 3, the ranks of the number of times of delivery include an upper rank with a higher number of issues per unit period, a lower rank with a lower number of issues per unit period, and the number of issues per unit period. It is composed of three ranks, a middle rank that is between a higher rank and a lower rank. When the storage means 13 is arranged in order from the type of articles with the highest number of issues per unit period as the sorting state, the first boundary line K1 between the upper rank and the middle rank indicates which type of article and which type. It is configured to store whether the second boundary line K2 between the middle rank and the lower rank is located between which kind of article and which kind of article. .

  A plurality of types of articles are arranged in order from the type of articles with the highest number of issues per unit period, and are divided into a plurality of issue times ranks of upper rank, middle rank, and lower rank. Each of the automatic warehouse equipments 1 is assigned with a number of delivery times ranks, and the storage means 13 determines which of the plurality of delivery time ranks of each automatic warehouse equipment 1 It is configured to store a delivery number rank assignment pattern that determines whether to assign a delivery number rank. For example, as shown in FIG. 4, the storage unit 13 stores the number-of-going-out rank assignment pattern in which a middle rank is assigned to the first automatic warehouse facility 1a and a higher rank and a lower rank are assigned to the second automatic warehouse facility 1b. It is the number-of-issues rank allocation pattern that is determined to allocate.

  When the calculation means 12 classifies a plurality of types of articles into a plurality of delivery frequency ranks based on the classification state stored in the storage means 13 in the delivery frequency rank assignment pattern stored in the storage means 13, At present, the number of types of articles corresponding to each rank and the ratio of the number of types of articles corresponding to each rank with respect to the number of types of all articles are calculated. That is, as shown in FIG. 3, when the calculation means 12 classifies the plurality of types of articles into the upper rank, the middle rank, and the lower rank according to the number of issues per unit period, how many are in each rank. It is calculated whether or not the type of article corresponds, and for each rank, the ratio of the number of types of articles corresponding to that rank to the number of types of all articles.

  The output unit 14 is configured to output to the display unit 15 the current number of types of articles and the ratio calculated by the calculation unit 12. Thereby, as shown in FIG. 5A, the display means 15 is configured to display the current number of types of articles (the number of items in the illustrated example) and the ratio.

  Here, with regard to the middle rank, there are two ranks in the middle rank, the first middle rank with a large number of issues per unit period and the second middle rank with a small number of issues per unit period. It is divided. Similarly to the middle rank, the lower rank is divided into two ranks of the first rank and the second rank in the lower rank. Therefore, the calculation means 12 calculates the number of types and the ratio of the current article in a state where each of the middle rank and the lower rank is divided into two ranks, the first rank and the second rank. As a result, as shown in FIG. 5 (a), the number of types of items (number of items) in the current state in the state where each of the middle rank and the lower rank is divided into two ranks of first and second ranks. And the ratio is displayed.

  When the calculation means 12 classifies a plurality of types of articles into a plurality of delivery frequency ranks based on the classification state stored in the storage means 13 in the delivery frequency rank assignment pattern stored in the storage means 13, In the present situation, the total number of times of delivery per unit period of articles assigned to each of the first automatic warehouse facility 1a and the second automatic warehouse facility 1b, and the automatic warehouse facilities It is comprised so that an outgoing ratio may be calculated. The output unit 14 is configured to output to the display unit 15 the current total number of times of delivery and the delivery ratio calculated by the calculation unit 12. As shown in FIG. 5B, the display means 15 displays the total number of times of delivery (the number of times of delivery in the illustrated example) and the rate of delivery in each of the first automatic warehouse facility 1a and the second automatic warehouse facility at present. It is configured as follows. Here, the outgoing ratio is the total number of outgoings per unit period (for example, one day) in the first automatic warehouse facility 1a as the total number of outgoings per unit period (for example, one day) in the second automatic warehouse facility 1b. The value is divided.

  When the calculation means 12 classifies a plurality of types of articles into a plurality of delivery frequency ranks based on the classification state stored in the storage means 13 in the delivery frequency rank assignment pattern stored in the storage means 13, It is configured to calculate the number of stored articles and the filling rate in each automatic warehouse facility 1 when the articles allocated to each of the first automatic warehouse facility 1a and the second automatic warehouse facility 1b are stored. . The output unit 14 is configured to output to the display unit 15 the number of stored articles and the filling rate for each of the first automatic warehouse facility 1a and the second automatic warehouse facility that are currently calculated by the calculation unit 12. . Thereby, as shown in FIG.5 (c), the display means 15 is the number of articles | goods (storage shelf in the illustration) and filling rate about each of the 1st automatic warehouse equipment 1a in the present, and a 2nd automatic warehouse equipment. Is configured to display. Incidentally, in FIG. 5C, the second automatic warehouse facility 1b is displayed divided into an article storage shelf 2 for high shelves and an article storage shelf 2 for low shelves. The number of shelves indicates the maximum number of articles that can be stored in the article storage shelf 2.

  Returning to FIG. 2, the allocation evaluation device W includes a classification state change setting unit 16 that can change and set the classification state of a plurality of delivery count ranks in addition to the input unit 11 and the calculation unit 12. The division state change setting means 16 changes and sets one or both of the number of types of items (number of items) in each rank and the ratio of the number of types of items in each rank with respect to the number of types of all items. It is configured to change and set the classification state of the number of times of delivery. That is, the operator can change and set the number of types of items (number of items) and the ratio in each rank in FIG. The position of each of the first boundary line K1 and the second boundary line K2 is changed and set.

  When the classification state change setting unit 16 changes and sets the classification state of a plurality of delivery frequency ranks, the calculation unit 12 changes the distribution state rank assignment pattern stored in the storage unit 13 with the division state change setting unit 16. When a plurality of types of articles are classified into a plurality of delivery times ranks based on the set classification state, the articles assigned to each of the first automatic warehouse equipment 1a and the second automatic warehouse equipment 1b after the change The total number of times of delivery per unit period and the delivery ratio between the automatic warehouse facilities 1 are calculated from the total number of times of delivery. The output means 14 is configured to output to the display means 15 the total number of times of delivery and the delivery ratio after the change calculated by the calculation means 12. As shown in FIG. 5 (b), the display means 15 displays the total number of times of delivery (the number of times of delivery in the illustrated example) and the delivery ratio of the first automatic warehouse facility 1a and the second automatic warehouse facility after the change. Is configured to do.

  Thereby, the worker can grasp what value the delivery ratio between the automatic warehouse equipments 1 becomes when the division state of the plurality of delivery frequency ranks is changed and set to what sort state. Therefore, the worker understands what value the distribution ratio between the automatic warehouse facilities 1 will be when the classification state of the plurality of output frequency ranks is set, and the multiple output frequency ranks. It is possible to repeatedly change and set the classification state. Here, for example, in order to have the same time for the first automatic warehouse facility 1a and the second automatic warehouse facility 1b in one day, the difference in the output capability between the automatic warehouse facilities 1 is eliminated. Thus, the delivery ratio between the automatic warehouse facilities 1 may be set as the target delivery ratio.

  For example, in this embodiment, the delivery capacity in the unit period (for example, one day) of the second automatic warehouse facility 1b is 1.5 times that of the first automatic warehouse facility 1a. Therefore, the target delivery ratio for eliminating the delivery capacity difference between the automatic warehouse equipments 1 is 67% obtained by dividing the delivery capacity of the first automatic warehouse equipment 1a in the unit period by the delivery capacity of the second automatic warehouse equipment 1b. (1.0 ÷ 1.5). Thereby, as shown in FIG. 5, the worker can change and set the classification state of a plurality of delivery frequency ranks by the division state change setting unit 16 so that the changed delivery ratio becomes 67%. When a change state of a plurality of delivery frequency ranks in which the changed delivery ratio becomes the target delivery ratio is set, the position of each of the first boundary line K1 and the second boundary line K2 in FIG. Is determined.

  In the delivery number rank allocation pattern stored in the storage means 13, a division state of a plurality of delivery number ranks in which the changed delivery ratio becomes the target delivery ratio is set, and plural kinds of articles are set in the set division state. Can be divided into a plurality of ranks of the number of times of delivery, and the delivery operation end time can be set to the same time for the first automatic warehouse facility 1a and the second automatic warehouse facility 1b in one day. In this way, for example, in order to set the exit time at the same time for a plurality of automatic warehouse facilities in one day, what sort of state should be set for the plurality of delivery rank ranks? By determining, it is possible to determine which kind of article among the plurality of kinds of articles should be assigned to each automatic warehouse facility 1.

  The computing means 12 classifies the plurality of types of articles into a plurality of delivery frequency ranks based on the classification status changed and set by the classification status change setting means 16 in the delivery frequency rank assignment pattern stored in the storage means 13. Sometimes, after the change, the number of stored articles and the filling rate in each automatic warehouse equipment 1 when the articles assigned to each of the first automatic warehouse equipment 1a and the second automatic warehouse equipment 1b are stored are calculated. It is configured. The output unit 14 is configured to output to the display unit 15 the number of stored articles and the filling rate for each of the first automatic warehouse facility 1a and the second automatic warehouse facility that are currently calculated by the calculation unit 12. . Thereby, as shown in FIG.5 (c), the display means 15 is the number of articles | goods (storage shelf in the illustration) and filling rate about each of the 1st automatic warehouse equipment 1a in the present, and a 2nd automatic warehouse equipment. Is configured to display.

  Thereby, the worker can set the respective filling ratios of the first automatic warehouse equipment 1a and the second automatic warehouse equipment in a state where a plurality of delivery frequency rank division states in which the changed delivery ratio becomes the target delivery ratio are set. It can be confirmed whether it exceeds 100%. Therefore, in order to set the same time for a plurality of automatic warehouse facilities, the delivery work end time is set to one day while keeping the filling rate of each of the first automatic warehouse facility 1a and the second automatic warehouse facility not exceeding 100%. In addition, it is possible to determine which kind of article among a plurality of kinds of articles should be assigned to each automatic warehouse facility 1.

  The allocation evaluation device W is configured to be able to output the sorting state by the output means 14 when setting a sorting state of a plurality of shipping number ranks in which the changed shipping rate becomes the target shipping rate. As a result, the host controller that controls the overall operation of the automatic warehouse facility 1 classifies a plurality of types of articles into a plurality of delivery times ranks in the classification state output by the output means 14 and stores them in the storage means 13. The delivery number rank is assigned to each of the first automatic warehouse facility 1a and the second automatic warehouse facility 1b so as to be the delivery number rank assignment pattern. The host control device then stores the first automatic warehouse facility 1a and the second automatic warehouse facility so as to store articles with the number of times of delivery assigned to the first automatic warehouse facility 1a and the second automatic warehouse facility 1b. It is configured to control each operation of 1b.

  That is, as shown in FIG. 4, the number-of-issues rank assignment pattern stored in the storage means 13 assigns a middle rank to the first automatic warehouse facility 1a and assigns a higher rank and a lower rank to the second automatic warehouse facility 1b. It is the number-of-issues rank allocation pattern determined to be allocated. Thus, for example, when a medium-rank article is carried into the article carry-in location 6 in the first automatic warehouse facility 1a, the article is transferred to the second article transport device 9 and the first article transport device in the first automatic warehouse facility 1a. 5 and is stored in the article storage shelf 2 of the first automatic warehouse facility 1a. When an article of a higher rank or a lower rank is carried into the article carry-in location 6 in the second automatic warehouse facility 1b, the article is transferred to the second article transport device 9 and the first article transport device 5 in the second automatic warehouse facility 1b. And is stored in the article storage shelf 2 of the second automatic warehouse facility 1b. When an article of higher rank or lower rank is carried into the article carrying place 6 in the first automatic warehouse facility 1a, the article is conveyed to the transfer conveyor 10 by the second article conveying device 9 in the first automatic warehouse facility 1a. And then transferred from the first automatic warehouse facility 1a to the second automatic warehouse facility 1b, and then transferred by the second article transfer device 9 and the first article transfer device 5 in the second automatic warehouse facility 1b. It is stored in the article storage shelf 2 of the facility 1b.

Instead of the setting means 16, a target delivery ratio setting means 17 is provided. The target delivery ratio setting means 17 indicates the number of delivery times per unit period of the articles assigned to each automatic warehouse equipment 1 when the articles are assigned to the first automatic warehouse equipment 1a and the second automatic warehouse equipment 1b. It is configured to be able to set a target delivery ratio between the automatic warehouse facilities 1 for the total number of delivery. That is, in the first embodiment, the target delivery ratio setting unit 17 sets the delivery ratio between the automatic warehouse facilities 1 to the ratio according to the ratio of the delivery capacity between the automatic warehouse facilities 1 as a target delivery ratio (for example, 67%). ) Can be set.

As in the allocation evaluation apparatus W in the first embodiment, the allocation evaluation apparatus W1 in the second embodiment also has the number of types (number of items) and ratios of articles in each rank as shown in FIG. The total number of times of delivery per unit period (number of times of delivery) in each automatic warehouse facility 1 is displayed.
Hereinafter, regarding the allocation evaluation apparatus W1 in the second embodiment, only the configuration different from the allocation evaluation apparatus W in the first embodiment will be described, and the description of the same configuration will be omitted.

  When the calculation means 12 classifies a plurality of types of articles into a plurality of delivery frequency ranks based on the classification state stored in the storage means 13 in the delivery frequency rank assignment pattern stored in the storage means 13, It is configured to obtain a delivery ratio between the automatic warehouse facilities from the total number of delivery times of articles assigned to each of the plurality of automatic warehouse facilities. And the calculating means 12 is comprised so that the division | segmentation state of several delivery frequency rank may be changed and set so that the calculated | required delivery ratio may become the target delivery ratio set in the target delivery ratio setting means 17. FIG. The storage unit 13 is configured to update and store the stored classification state to the classification state changed and set by the calculation unit 12. The output unit 14 is configured to output the classification state changed and set by the calculation unit 12 to the display unit 15. As shown in FIG. 3, the display means 15 is configured to display the first boundary line K1 and the second boundary line K2 in the changed and set division state. Here, for example, the display unit 15 can display not only the changed and set division state but also a display indicating how the change has been made from now. For example, the display unit 15 first displays the current first boundary line K1 and second boundary line K2. When the division state changed and set by the calculation means 12 is output by the output means 14, the display means 15 raises and lowers the first boundary line K1 and the second boundary line K2 to change and set the division state. The first boundary line K1 and the second boundary line K2 are displayed.

Based on FIG. 3, the change setting of a division | segmentation state is demonstrated.
The computing means 12 repeatedly changes and sets the positions of the first boundary line K1 and the second boundary line K2 in the delivery frequency rank assignment pattern stored in the storage means 13, and sets the delivery ratio for each of the changed settings. The combination of the 1st boundary line K1 and the 2nd boundary line K2 from which the delivery ratio becomes a target delivery ratio is calculated | required. Thereby, the calculation means 12 calculates the division state of a plurality of delivery count ranks in which the delivery ratio becomes the target delivery ratio set by the target delivery ratio setting means 17. For example, the calculation means 12 temporarily sets the first boundary line K1 to a certain position, repeatedly changes and sets the position of the second boundary line K2, obtains a shipping ratio for each of the changed settings, and the shipping ratio is the target shipping ratio. The position of the second boundary line K2 is obtained. The computing means 12 temporarily sets the first boundary line K1 at a certain position and repeats the process of obtaining the second boundary line K2, thereby the first boundary line K1 and the second boundary line at which the shipping ratio becomes the target shipping ratio. Find the combination with K2.

When there are a plurality of combinations of the first boundary line K1 and the second boundary line K2 obtained, the calculation means 12 calculates an optimum combination from the plurality of combinations. For example, the computing means 12 is assigned to each of the first automatic warehouse facility 1a and the second automatic warehouse facility 1b for each of a plurality of combinations of the first boundary line K1 and the second boundary line K2. The filling rates of the first automatic warehouse facility 1a and the second automatic warehouse facility 1b when the articles are stored are calculated. Thereby, the calculation means 12 determines whether there is a combination in which the filling rate of each of the first automatic warehouse facility 1a and the second automatic warehouse facility 1b exceeds 100%, and the combination in which the filling rate exceeds 100%. Excluded.
Further, the calculation means 12 determines how many articles should be moved from the current storage state when each of the plurality of combinations of the first boundary line K1 and the second boundary line K2 is the combination. The number of moving articles is calculated. In other words, depending on the combination of the first boundary line K1 and the second boundary line K2, for example, it is necessary to store articles currently stored in the first automatic warehouse facility 1a in the second automatic warehouse facility 1b. For this purpose, the article must be moved from the first automatic warehouse facility 1a to the second automatic warehouse facility 1b. Therefore, the calculation means 12 calculates the number of moving articles for each of the plurality of combinations of the first boundary line K1 and the second boundary line K2, and calculates the combination having the smallest number of moving articles as the optimal combination. is doing.

  As described above, when the operator sets the target delivery ratio for eliminating the delivery capability difference between the automatic warehouse facilities 1 by the target delivery ratio setting means 17, the plurality of delivery frequency ranks changed and set by the calculation means 12. Are updated and stored in the storage means 13. Since the classification state of the plurality of delivery frequency ranks updated and stored in the storage means 13 is displayed on the display means 15, the worker can issue a plurality of deliverys in which the delivery ratio between the automatic warehouse facilities 1 becomes the target delivery ratio. It is possible to determine what sort state the number rank classification state is. In addition, since it is only necessary to set the target delivery ratio with the target delivery ratio setting means 17, the work can be simplified.

  The allocation evaluation device W1 is configured to be able to output the changed and set classification state by the output means 14 when the classification state of a plurality of delivery number ranks whose delivery ratio becomes the target delivery ratio is changed. As a result, the host controller that controls the overall operation of the automatic warehouse facility 1 classifies a plurality of types of articles into a plurality of delivery times ranks in the classification state output by the output means 14 and stores them in the storage means 13. The delivery number rank is assigned to each of the first automatic warehouse facility 1a and the second automatic warehouse facility 1b so as to be the delivery number rank assignment pattern.
